\ To all whom it may concern:

. frames and between are Be it known that I, .MARTIN KUNO SACHS, a citizen of the United States, and a resident of Houston, in the county of Harris and State of Texas, have invented a new and Improved. Brick-Truck, of which the following is a full, clear, and exact description.

My invention relates to a truck which, al-

.though capable of many uses, has been desi ned wit special reference to the transfer of bricks along a track and on pallets or drying boards. It will therefore be described with special reference to this purpose, although it is to be understood thatit is not limited in this res ect. t

he principal object of the invention is to provide means whereby a truck can be moved under a load, the load readily lifted from its place and leftin an elevated position upon the truck, and the truck moved away. Further obliects of the invention relating to this one wi l a pear below.

- Re erence is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference designate corresponding parts in all the figures.

Figure 1 is a perspective view of a truck, the invention. Fig. 2 is a sectional view'o the same on the line 2 2 of Fig. 4. Fig. 3 is a sectional view on the line 8 3 of Fig. 2, and Fig. 4 is a central longitudinal section of the same.

The truckis provided with the usual wheels 10 on axles 11 for supporting the frame, which is shown as consisting of two rectangular structures 12 and 13, formed of metal or Wood. These two structures are separated from each other by blocks 14 and are located in the same plane, the inner one being secured to the outer one, in any desired manner. The axles pass through both rovided with rollerbcarings 15, which in t e present form are shown as rooved Wheels. Above the main frame of t is truck ll mount a movablcframc 16, having brackets 17 upon its under side,

Each of these surfaces is provided with a scg mental portion 19 at the bottom and 21 segmental portion 20 at the top for rece ving the .roller-bearings, and it will be seen that the frame will readily rest in either the upper or lower position on the hearings on account of the curved shape of these upper and lower surfaces.

In order to raise and lower the movable frame, I provide means for moving it longi tudinally with respect to the main frame. This longitddinal movement on account of the inclined surfaces 18 results in a simultaneousvertical movement. In order to a(-. complish this result, I rovide apivot 21 upon the end of the movab e frame, and to this I connect a link 22. This link is in turn pivotally connected by a stud 23 with a nut 24. This nut is provided with internal screwthreads and cooperates with a screw 25, which is provided with collars 26, adapted to on age the opposite sides of a plate 27,*which is coated upon the end of the outer frame 13. A hand wheel or crank 28 is connected with the screw, and it will be readily obvious that the rotation of the screw will cause they recip rocation of the movable frame 16, and conseuently the raising and lowering of the latter. l t guard 29 is located about the nut 24, and this guard is connected with the stationary frame. Stops 30 are also provided for the movable frame, these stops having hooks 31 adapted to engage the stationary frame. The construction and operation of the device should be clear from the above description.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A truck comprising a frame, a pair of shafts journalcd on said frame, a roller-beariup; mounted upon each of said shafts, and a movable frame mounted above the main frame and n'ovidcd with downwardly-extending brac ets, said brackets having tracks for receiving said roller-bearings.

.5. A truck comprising a frame, a pair of shafts jourualcd on said frame, a roller-beariu mounted upon each of said shafts, a movab c frame mounted abovethc main frame and provided. with'downwardly'extendiug ceiving said rolIcy-bearings, and means for h moving said movable frame comprising i1 screw connected with the main frame, and a nut connected with the movable frame and cooperating with the screw for moving the letter.

i 3. A truck comprising a frame, flpair of shafts journuled on said frame, it roller-bearin mounted upon each of said shafts, a movub e frame mounted. above the main frame and provided with downWardly-extendi11g brackets, said brackets having trucks for receiving said roller-beatings, means for reciprocating said movable frame, and :1 series of stops on the movable l'rume, sch stop comprising a hook adapted to engage the stntiona ry frame.

4. A truck, comprising a main frame con- I sisting of two rectangular structures separated from each other, a of axles upon i winch the mum frame 18 mounted, a rollerbearing upon each end of each axle, located between said structures, a movable frame mounted on the mum frame and provided with a bracket having an inclined surface located over each of said bearings, a screw connected with the mom frame, and a nut connected with the movable frame and cooperl I l i I name to this specification in the with the screw for moving the movable frame, and a it of stops eeelt having a hook and mounted on the movable frame, said hooks bemg adapted to engage the stationin frame when the frame is in its highest po' sirion,

In testimony whereof I have signed "my presence of two subscribing witnesses. 1
